NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented June 11, 1907.

lk plicati n fil d September 24. 1906. Serial No. 335,866.

To all whom it may concern.-

Be it known that I, FREDERICK W. J OHN- SON, .a citizen of the United States, residing at WValtham, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention relates to certain improvements in the device for preventing the refilling of bottles for which Letters Patent of the United States No. 701,048 and No. 737,633 were granted to me May 27, 1902, and September 1, 1903, respectively, and has for its object to secure greater freedom in the outpour from the bottle and also to more effectually prevent the possibility of refilling the bottle after the same has been emptied.

The invention consists in certain novel features and details of construction as hereinafter more fully described, and pointed out in the claims.

Referring to the drawings: Figure 1 is a section, partly in elevation, through the neck of a bottle having my improved device applied thereto, the bottle being broken away to save space. Fig. 2 is a section similar to Fig. 1 showing the position of the parts when the'bottle is tipped to pour out the liquid which it contains. Fig. 3 is an enlarged section, partly in elevation, taken on line 33, Fig. 1. Fig. 4 is an enlarged section, taken on line 4-4, Fig. 1. Fig. 5 is a perspective view of the device removed from the bottle neck. Fig. 6 is another perspective view of the device showing the opposite side thereof from that illustrated in Fig. 5. Fig. 7 is a diagram view illustrating a development of the periphery of the cylindrical casing or sleeve.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 10 is the bottle neck.

11 is a cylindrical sleeve which is inserted in the neck of the bottle and securely fas tened thereto by cement or otherwise as may be desired. The sleeve 11 has an interior chamber 12, the upper end of which is closed by a plug 13 fast thereto by a pin 13. In the lower end of said chamber is a cylindrical valve 14 adapted to rest, when the bottle is in a vertical position as shown in Fig. 1, upon an annular valve seat 15 formed upon the inner wall of the sleeve 11. Two ports or openings 16, 16 11 which open from the interior chamber 12 are provided in the sleeve to an external chamber 17 which is formed in the periphery of said sleeve, said ports being in alinemont with each other longitudinally of said sleeve. The chamber 17 has an outlet passage 18 extending therefrom to the upper edge of the sleeve 17.

The passage 18 is that through which the liquid flows out of the bottle as hereinafter described. An air passage 19 is provided in the periphery of the sleeve 11 extending longitudinally thereof from the top of the sleeve toward the lower end and below the ports 16, said passage being preferably formed at its lower end upon a curve and terminating within the lower end of the external chamber 17. Two vent passages 20 and 21 extend from the top of the cylindrical sleeve 11 downwardly along the periphery thereof and through said sleeve terminating adjacent to the lower end of the plug 13, said lug being cut away at the lower end thereof. The object of these vent passages is to give free movement to the valve 14 under all conditions so that said valve may move freely within the interior chamber 12 when the bottle is tipped from the position shown in Fig. 1 to that shown in Fig. 2 or vice versa. If it were not for these vent passages an air cushion might be formed or liquid would remain in the interior chamber 12 between the valve 14 and the plug 13 after the valve had passed the ports 16 when the bottle is in the inclined position shown in Fig. 2 and in reversing the bottle from the inclined position to the upright position the valve would be prevented from freely dropping to its seat 16 by reason of a vacuum being formed in the interior chamber 12 between said valve and the plug 13. The vents 20 and 21 effectually prevent any such interference with the free move' ment of the valve longitudinally of the interior chamber.

Under normal conditions when the bottle is in the position illustrated in Fig. 1, the valve rests upon the annular valve seat 15 and when in this position it will be seen that it would be impossible to introduce a wire into the interior of the sleeve 11 for the purpose of lifting the valve from its seat and intpoducing liquid into the interior of the bott e.

Assuming the bottle to be filled with liquid and it is desired to pour some of said liquid out of the bottle, the bottle is inclined to the position illustrated in Fig. 2. The valve 14 will slide down the interior of the sleeve in the chamber 12 until it rests against the plug 13 as shown in Fig. 2. The bottle is held, in order to secure the best result, with the air passage 19 upon the upper side of the neck. When in this position the liquid passes into the interior chamber 12 outwardly therefrom through the ports 16 into the external chamber 17 and through the passage 18 out of the bottle. The liquid will flow freely from the bottle through the passages clescribed for the reason that the air entering the bottle passes through the air passage 19 and into the opposite end of the external chamber 17 from that at which the outward passage 18 for the liquid is located. As the liquid flows out of the bottle, the air passes into the same through the air passage 19 and through the upper part of one of the ports 16, thus preventing any vacuum forming in the bottle which would interfere with the free flow of the liquid outwardly therefrom.

l/Vhile I have shown a plurality of ports leading from the exterior .to the interior chamber of the cylindrical sleeve, it is evident that a single port may be used without departing from the spirit of my invention, although for practical purposes it is preferable to use a series of ports arranged in a straight line on one side only of the sleeve, as shown in the drawings.

Having thus described my invention, What I claim and desire by Letters Patent to secure is:

1. The combination with a bottle neck of a cylindrical sleeve fast thereto, said sleeve having an interior chamber opening through the inner end of said sleeve and having an exterior chamber connected to said interior cham ber by ports arranged in a single straight line on one side only of said sleeve, said sleeve provided with an outlet passage leading from the outer end of said exterior chamber to the outer end of said sleeve, and with an air passage leading fiom the outer end of said sleeve to the inner end of said exterior chamber, and a valve slidable longitudinally within said interior chamber and adapted to rest normally upon a seat provided therein.

2. The combination with a bottle neck of a cylindrical sleeve fast thereto, said sleeve having an interior chamber opening through the inner end of said sleeve, a plug fast to said sleeve at the outer end thereof and within said interior chamber, said sleeve having an exterior chamber connected to said inner chamber by ports arranged in a single straight line extending longitudinally of said sleeve on one side only thereof, said sleeve provided with an outlet passage leading from the outer end of said exterior chamber to the outer end of said sleeve, and with an air passage leading from the outer end of said sleeve to the inner end of said exterior chamber, and a valve slidable longitudinally Within said interior chamber and adapted to rest normally upon a seat provided therein.

3. The combination with a bottle neck of a cylindrical sleeve fast thereto, said sleeve having an interior chamber opening through the inner end thereof and within said interior chamber, said sleeve having an exterior chamber connected to said inner chamber by ports arranged in a single straight line extending longitudinally of said sleeve on one side only thereof, said sleeve provided with an outlet passage leading from the outer end of said exterior chamber to the outer end of said sleeve, and with an air passage leading from the outer end of said sleeve to the inner end of said exterior chamber, and a valve slidable longitudinally within said interior chamber and adapted to rest normally upon a seat provided therein, said sleeve provided with a vent passage extending from the lower end of said plug to the outer end of said sleeve and opening into said interior chamber.

4. The combination with a bottle neck of a cylindrical sleeve fast thereto, said sleeve having an interior chamber opening through the inner end of said sleeve and having an exterior chamber connected to said interior chamber by a port, said sleeve provided with an outlet passage leading from the outer end of said exterior chamber to the outer end of said sleeve, and with an air passage leading from the outer end of said sleeve to the inner end' of said exterior chamber, and. a valve slidable longitudinally within said interior chamber and adapted to rest normally upon a seat provided therein.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
